Current through Register Vol. 35, No. 11, June 11, 2024

Section 20.2.19.109 - ALLOWABLE EMISSIONS

A. The owner or operator of new potash, salt or sodium sulfate processing equipment shall not permit, cause, suffer or allow particulate matter emissions to the atmosphere:

(1) to exceed 0.10 grains per dry cubic foot of discharge gas adjusted to standard conditions from dryers; or

(2) to exceed 0.04 grains per dry cubic foot of discharge gas adjusted to standard conditions from all other processing equipment.

B. The owner or operator of existing potash, salt or sodium sulfate processing equipment shall not permit, cause, suffer or allow particulate matter emissions to the atmosphere:

(1) in excess of a total of 90 pounds per hour from all stacks serving equipment used in drying muriate of potash and all associated compactor operations;

(2) in excess of a total of 90 pounds per hour from all stacks serving equipment used in drying langbeinite;

(3) in excess of a total of 35 pounds per hour from all stacks serving equipment used in drying sulfate of potash and associated screening operations;

(4) in excess of a total of 15 pounds per hour from all stacks serving equipment used in dry milling of fine langbeinite; and

(5) in excess of a total of 50 pounds per hour from all stacks serving equipment used in drying salt or sodium sulfate.

C. The owner or operator of existing potash, salt or sodium sulfate processing equipment shall not permit, cause, suffer or allow particulate matter emissions to the atmosphere in excess of a total of 30 pounds per hour from all stacks serving evaporators.

D. The owner or operator of existing potash, salt or sodium sulfate processing equipment shall not permit, cause, suffer or allow particulate matter emissions from any equipment not regulated by subsections A, B, or C of 20.2.19.109 NMAC to exceed the allowable rates specified within Table 1.

(1) Interpolation of rates not specified within the table shall be accomplished by use of the equation: E = 0.045 times q raised to the power 0.62, where E is the allowable emission rate expressed in pounds per hour and q is the stack volumetric flow rate expressed in dry cubic feet per minute adjusted to standard conditions.

(2) Table 1 - Allowable Particulate Emission Rates for Specific Stack Volumetric Flow Rates:

Volumetric Flow Rate (dscfm)	Allowable Emission Rate (lb/hr)
1,000 or less	3.3
2,000	5.0
4,000	7.7
6,000	9.9
8,000	11.8
10,000	13.6
20,000	20.9
30,000	26.9
40,000	32.1
50,000	36.9
60,000	41.3
70,000 or greater	45.4
